Title: Engagement device and automatic document feeder using the same
Inventor: OBARA TOSHIMITSU
IPC: F16D27/118
Filed: 1999-03-03
Abstract: PROBLEM TO BE SOLVED: To surely transmit a drive force by a simple constitution by providing a first inferior engagement prevention part having inclined face connecting a tooth part end part to a tooth surface in a second gear side tooth part of a first gear and axially moving one or the both of the gears. SOLUTION: When an electromagnet is energized and a tooth part 411 of a driven gear is moved in an A direction by the movement of a clutch plate, the end part 413 and the end part 423 of a drive gear are approached to each other and the inclined surfaces 422, 412 are brought in contact with each other by the rotation of the drive gear. The inclined surface 412 is moved in the D direction, the driven gear is moved in the A direction, and the tooth surface 418 is brought in contact with a tooth surface 428 so that the driven gear and the drive gear are surely in an engaged state. When stopping the energization, the clutch plate is moved in the inverse A direction along with the driven gear by a spring of the driven gear so that the engagement between the drive gear and the driven gear is released. The inclined surfaces 412, 422 prevent the inferior engagement between the tooth parts 411, 421 so that, even if the non- rotating driven gear is engaged with the drive gear rotating at high speed, the idle rotation can be prevented and the structure is simple.

Title: Hydrogen storage alloy electrode and its manufacture
Inventor: MATSUURA YOSHINORI
IPC: H01M4/24
Filed: 1997-03-11
Abstract: PROBLEM TO BE SOLVED: To provide a hydrogen storage alloy electrode in which plural hydrogen storage alloy layers are provided on a collector, and a layer on the collector side is formed by excellently hydrophilic hydrogen storage alloy, while a layer on the electrolyte side is formed by hydrophobic hydrogen storage alloy, so that discharge characteristic with high efficiency can be secured without raising internal pressure. SOLUTION: A hydrogen storage alloy forming a hydrogen storage alloy layer (inside layer) 14 on the side of a collector 12 is made hydrophilic by applying acid treatment or alkaline treatment. Accordingly, charging and discharging reaction occurs actively between the inside layer 14 and the collector 12, and high efficiency of discharge characteristics can be achieved. Since neither acid treatment or alkali treatment is applied to hydrogen storage alloy forming a layer (outside layer) 16 on the side in contact with electrolyte, it is kept hydrophobic. Accordingly, an internal pressure rise can be suppressed since oxygen gas absorbing reaction occurs actively when charged excessively. Preferable hydrogen storage alloy is expressed by a general formula ABx , and x is 4.4-5.4, A is mish metal and B is Ni and the like.

Title: Signal processing method for thermal type flow rate sensor
Inventor: TANIMOTO KOJI
IPC: G01F1/68
Filed: 1989-03-08
Abstract: PURPOSE:To improve the responsiveness for measuring a flow rate by executing the operation by using a correction ratio value which is varied in accordance with a flow rate variation quantity. CONSTITUTION:A signal processor 9 executes a correcting operation by various sensors, mainly on an air flow rate signal from an air flow rate sensor 1 contained in a suction passage 2, and an engine revolution speed signal from a crank angle sensor 8, and controls injection pulse width of an injector 7. That is, the processor 9 allows an output of the sensor 1 to store in advance a first arithmetic value CQmax generated in a balanced state of this output. By using a correction ratio value DELTAC which is varied in accordance with a variation of this arithmetic value CQmax and a large/small relation to the arithmetic value CQmax, and also, in accordance with a flow rate variation quantity DELTAQ, a second arithmetic value CQ is formed. Subsequently, by calculating a correction coefficient C by these arithmetic values, and executing the correction by multiplying the output of the sensor 1 by the coefficient C, a thermal influence by a holding member for supporting a temperature dependency resistance is obviated, and a response characteristic at the time of detecting an air flow rate is improved.

Title: Method for orienting magnetic powder
Inventor: SAGAWA MASATO
IPC: B30B15/02
Filed: 1996-02-20
Abstract: PROBLEM TO BE SOLVED: To provide a method for orienting magnetic powder by which the degree of orientation much higher than the degree of orientation obtd. by impressing a pulse magnetic field of one direction on the magnetic powder packed in a rubber mold to orient the magnetic powder is obtainable. SOLUTION: The orientation of the magnetic powder is executed by impressing the magnetic field generated by passing a current to an orienting magnetic field generating coil 4 on the magnetic powder (m) packed in the rubber mold l. At this time, the current to be passed to this orienting magnetic field generating coil is the alternately attenuating current generated at the time when the charge charged in a capacitor is discharged to the orienting magnetic field generating coil. In addition, the current to be passed to the orienting magnetic field generating coil is made zero or is attenuated in a non-inverted state after the alternating attenuating current is attenuated to the specified value.  The current is made zero or is attenuated in the non-inverted state when the alternating attenuating current is attenuated to the specified value and, therefore, the heat generation in the coil is lessened and the shorter charging time of the charge to the capacitor is necessitated. The molding cycle of a green compact is thus shortened.

Title: Device for converting object into primitive
Inventor: WATANABE KANEHIDE
IPC: G06T19/00
Filed: 1998-03-09
Abstract: PROBLEM TO BE SOLVED: To convert the object of a body of rotation to the primitive of the body of rotation by deciding whether or not the polygon-approximated object is the body of rotation. SOLUTION: From CAD data of the object, the coordinates of all vertexes constituting the object are acquired (S202). Two vertexes are selected from the vertex group and the distance between the two vertexes is found. The calculation of the distance is carried out (S204) for all possible combinations of two vertexes (called 'vertex pair'). The maximum value of the distance of each vertex pair is calculated (S206). The number of pairs having the distance equal to the maximum value found in S206 among the respective vertex pairs is found and it is decided (S208) whether the number of the pairs is larger than a specific threshold value. When the number of the pairs is larger than the threshold value, it is decided that the object is a body of rotation.  In this case, the radii and center points of the top and reverse surfaces of the body of rotation are found from the coordinates of the vertexes. Those values are shape parameters of the primitive.

IPC: G06F9/46
Filed: 1990-03-07
Abstract: PURPOSE:To easily decide the occurring position of a CPU interruption by outputting the position of the change signal that causes the interruption to a parallel input port led to the CPU in the number numerical value in the conditions where 2 or more change signals never produces the interruptions at one time. CONSTITUTION:The (n) sets of signal changing point detection circuits 11 - 1n detect the changes of the input signals and output these changes to an OR circuit 30 and a change signal position output circuit 50 as the changing signals. The circuit 30 outputs the changing signals to a CPU 20 as the interruption requiring signals. Then an interruption requirement is produced to the CPU 20 in the case of the change of either one of (n) sets of input signals. Meanwhile the circuit 50 receives the changing signals and converts the positions of the origins of transmission into the integer number values including the numerical values(1-n) and then turns these numerical values into the digital binary codes to output the changing signal position code of log2n to a parallel input port 40. In such a constitution, the CPU 20 can directly read the positions of the changing signals out of the port 40 based on the number numerical values of the digital codes at the reception of an interruption requiring signal.
